The first photographic evidence of this shape was obtained in 1952, when scientist Rosalind Franklin used a process called X-ray diffraction to capture images of DNA molecules (Figure 5).

In its structure, DNA contains a pattern for producing ... get them to do the work of DNA replication. The process is called the DNA polymerase chain reaction (PCR). (If it sounds familiar ...

so it can be directly compared with the double helical structure of DNA that everyone is familiar with. In switchback DNA, ...

The structure so perfectly fit the experimental data that it was almost immediately accepted. DNA's discovery has been called the most important biological work of the last 100 years, and the ...

DNA molecules are large and complex ... Each gene might have different forms, and these are called alleles. The gene for eye colour has an allele for blue eye colour and an allele for brown ...

But they were not the only ones working on finding its structure. They were competing with a team at King's College London, who were using a new technique called crystallography to study DNA.
